A bekishe, bekeshe or beketche (Yiddish: בעקעטשע‎ or בעקישע), is a type of frock coat, usually made of black silk or polyester, worn by Hasidic Jews, and by some non-Hasidic Haredi Jews. The bekishe is worn mainly on Shabbos and Jewish holidays, or at weddings and other such events. During the week, it is customary to wear a rekel, made of wool or polyester, looking like a regular double-breasted suit, only longer. Hassidic rabbis who wear a bekishe during the week will wear a more ornate version for Shabbos, often lined with velvet or some color other than or in addition to black.
